The growing interest in wireless high-data-rate communications at millimeter waves for both terrestrial networks and satellite is stimulating novel solutions to overcome the strong atmospheric attenuation. In particular, development of high-throughput communication systems Internet distribution fundamental complementing cover regions not connected backbones, such as sea or remote areas. Ku-band Ka-band are presently available. Recently, W-band (71-76 GHz 81-86 GHz) has been allocated...
The compact linear accelerator for research and applications (CLARA) is an ultrabright electron beam test facility being developed at STFC Daresbury Laboratory. ultimate aim of CLARA to advanced free laser (FEL) schemes that can later be implemented on existing future short-wavelength FELs. In addition, a unique provide high-quality novel concepts ideas in wide range disciplines function as technology demonstrator United Kingdom x-ray FEL facility. built three phases; the first phase, or...
Machine protection systems in high power particle accelerators are crucial. They can detect, prevent, and respond to events which would otherwise cause damage significant downtime accelerator infrastructure. Current often resource heavy operationally expensive, reacting after an event has begun damage; this leads facilities only covering certain operational modes setting lower limits on machine performance. Presented here is a new type of system based upon optical fibres, be complementary...
The pBR322 plasmid DNA was irradiated with 35 MeV electrons, 228 protons and 300 kVp X-rays to quantify damage make comparisons of between radiation modalities. Plasmid in a medium containing hydroxyl radical scavengers varying concentrations. This altered the amount indirect hydroxyl-mediated damage, create an environment that is more closely associated biological cell. We show increasing scavenger concentration significantly reduced post-irradiation consistently equally three At low...
The main obstacle to the practical implementation of dielectric wakefield acceleration (DWA) concept is development beam breakup instability due transverse dipole wakefields generated when propagates off axis in accelerating structure. One methods suppress this elliptically shape and accelerate it a planar Here, we report detailed experimental investigation dynamics elliptical beams structure with parameters mimicking future DWA modules. Both quadrupole wakefields' effects on stability...
A microfabrication process has been developed by using ultraviolet photolithography (UV-LIGA) with multi-layer SU-8 photoresist to create high aspect ratio Slow Wave Structures (SWS) for millimeter waves and THz vacuum electron devices. The main steps of the will be described, applied fabrication a double corrugated waveguide at 300 GHz..
Electrons are emerging as a strong complement to X-rays for diffraction based studies. In this paper we investigate the performance of JUNGFRAU detector with 320 um thick silicon sensor at pulsed electron source. Originally developed X-ray detection free lasers, features dynamic range 120 MeV/pixel (implemented in-pixel gain switching) which translated about 1200 incident electrons per pixel and frame in MeV region. We preset basic characteristics such energy deposited particle, resulting...
